I think I have successfully created a library project ActionBarShirlock (4.3.1). Then when I attempt to add it to my app by clicking properties > android then clicking on the "Add" button, I see a box saying "Please select a library project" and I select "actionbarshirlock". actionbarshirlock then appears in my list of libraries accompanied by a large green tick to the left of it. I click "ok". But then If I immediately go back to the properties dialog, I see a large red cross where the green tick used to be.
What happened?
EDIT: I noticed that in the latest release (4.3.1) of ActionBarShirlock, the directory structure within the zip file you download from actionbarsherlock.com is different from how it used to be in earlier versions, and so some tutorials of how to install it are no longer valid. So I had better explain how I created the library in the first place...
Step 1. I downloaded the zip file and expanded it into c:\android stuff\JakeWharton-ActionBarSherlock-071a61c
Step 2. From eclipse I clicked file > new > other > android > android project from existing code. Then next.
Step 3. From the "Iport projects" dialog, I clicked browse, then navigated to "C:\android stuff\JakeWharton-ActionBarSherlock-071a61c\actionbarsherlock" and clicked "ok".
Step 4. I now see "actionbarshirlock" in the "new project name" list, the tick box to the left is already ticked. ("copy projects into workspace" is not selected). I click "Finish"
Step 5. In package explorer I now see actionbarshirlock in my list of projects. I then to clean all projects and build all. There are no errors or warnings in my "Problems" tab.
Thats' it.
